HDFSPArrayMissField.h

// This file is part of the hdf4 data handler for the OPeNDAP data server.
// It retrieves the missing fields for some special NASA HDF4 data products.
// The products include TRMML2_V6,TRMML3B_V6,CER_AVG,CER_ES4,CER_CDAY,CER_CGEO,CER_SRB,CER_SYN,CER_ZAVG,OBPGL2,OBPGL3
// To know more information about these products,check HDFSP.h.
// Some third-dimension coordinate variable values are not provided.
// What we do here is to provide natural number series(1,2,3, ...) for
// these missing values. It doesn't make sense to visualize or analyze
// with vertical cross-section. One can check the data level by level.
